Are there any stable 4GB non-SDHC cards that will work with R4 at a sustainable frame rate?? If so, could you post a link to buy one.. Preferably Australian site.. Thanks if you can.. Sorry if there isnt any.. Just asking..

And dont tell me to update, Im happy with my R4.. Just want a bigger sd if possible..

You could try the dstt for update at around USD $12. The supercard would be a great choice at around USD $26. There is also the cyclods at around 55;(which many people think to be the best flashcart). You probably shouldn't bother buying a r4 clone with sdhc support.
